Nick seems to be describing something about Gatsby without complete awe; his description of all the things that go in and out of his house without once saying that Gatsby was amazing in some way. Gatsby is extravagant in every way possible. Again, Nick only seems to notice other men. Gatsby is really mysterious, and no one seems to know his story or ever has met him. While Nick was personally invited to the party, all other attendees just showed up for the fun of it and never really know or seem to truly care who Gatsby really is, but Nick does.
